I think that all that we need to do to fix this problem is to cache the preserved filters in the AbstractFocusViewAction. I will look into doing this as it should be a simple fix.
I was finally able to reproduce this. It turns out that I had the interest decorator on that prevented me from seeing this problem. This is now fixed by caching the preserved filters and adding a flag of whether we should try to cache the filters. This will prevent Context core from loading the extensions, which in turn loads the resource bridge plugin.
